I am using Aria more often than 167, but I haven't noticed any differences. I've just compared them and I stil don't know which is "easier", for me they are equal. Both cameras share the same matte screens, FU-x.
If I were you, I would rather choose on basis of size, weight and ergonomy of those cameras. I prefer Aria for smaller lenses (or everyday use) and RX for more serious shooting. 167 is waiting for sale
It included a super giant-screen (60mm film) movie which nicely merged some current footage with films and glass-plate prints taken by Frank Hurley. I'm sure everyone has seen one or more ex&les of his work from that trip, including night flash-powder shots of the ship, etc.

The plates and movie film were made in 1915 and underwent a harrowing trip across the ice in boats and sleds, and for 2 years on an isolated beach.
Getting to the bottom line, I thought that the prints (about 11X14) had all the detail, tonal range, and overall photographic impact as any B&W prints I have ever seen from present day technology.
